FASTENER.

Application led June 14,

This invention aims to provide an i1nproved separable fastener.

Fi 2 is a section on the line 2-2 oi' Fig. 1, being partly in elevation;

Fig.`3 is a se tion similar to Fig. 2, showing the relation of the partsof the stud when being unlocked from the socket;

Fig. `4 is a section similar to Fig. 2, showing the relation of theparts of the stud when the head is being entered into the studreceivingaperture;

Fig. 2.

Referring to the drawings and to the preferred form of my invention, asillustrated, 1 have shown a socket 1 including a studreceiving aperture,sealing means, and an attaching screw 2 for attachingy the socket to thebody 3 of an automobile, substantially as illustrated and described inthe copending application of Andrew G. Anderson, Serial No. 708,724.

The stud may be secured to the curtain 4 of an automobile in anysuitable manner, but I prefer to provide a back, plate 5, located uponthat side of the curtain nearest the socket, presenting a plurality ofattaching prongs 6 which pass through the curtain 4 and are clenchedpreferably outwardly and downwardly by a clench plate 7 located upon theopposite side of the cui tain. This clench plate also presents anelongated aperture 8, the purposes of which are more fully hereinafterdescribed.

The preferred form of socket-engaging means includes a socket-engagingmember presenting a head 9 having a neck 10 .for engagement with thesocket and a locking member 11 slidably mounted within the head andpresenting a fin-like part 12 through a longitudinal slot 13 located inthe head diametrically opposite the neck 10. This locking memberv isnormally `urged forward by a spring 14 interposed between one end of theline 5*-5 of Fig.

7 is a section on the line 7-7 of Fig.

. the locking member 11 and the inner face A of a cap 15, which fitsover the end of the 1924. Serial N0. 719,934.

socket-engaging member, thereby holding the spring in place andpresenting a finished appearance to the stud when assembled to thecurtain, as illustrated. in Fig. 1.

To permit relative tipping movement between the clench plate 7, curtain4 and back plate 5 as a unit or casing and the socketengaging means, Ihave provided a substantially deep recess 16 in the head 9 which isadapted to receive the pivot 17 located o u the back plate adjacent thetop of the preferably rectangular aperture 18 in the back plate throughwhich the head passes. This pivot is provided by a reversely bentportion which presents a smooth rounded surface for cooperation with therecess 1G. The wall at the bottom side of the aperture presents areversely bent edge for normal engagement` d with the in-like part 12 ofthe locking member and, also for engagement with the depending finger19, when the back plate is pivoted relative to the socket-enga means, asmore fully hereinafter described.

Assembly `of the parts of the stud is as follows. The socket-engaginghead 9 is first entered through the aperture 18 in the back plate 5until the recess 16 is opposite the pivot 17 and the locking member 11is then placed in the head 9 with the nlike part 12 projecting throughthe slot 13. Vhen pushed forward, the fin-like part engages theperiphery of the rectangular aperture 18 diametrically opposite thepivot 17 and urges the pivot into the recess 1G, thus hold-l ing theback plate and head together as illustrated in Figs. 2, 3 and 4@ Nextthe spring 14 is placed in the socket-engaging member and the cap isdriven over the outside of the socket-engaging member, thereby holdingall of the above-mentioned parts in place prior to assembly thereof to acurtain.

The stud may be vsecured to the socket by pressure upon the cap, whichprojects through the elongated aperture in the clench plate, thus urgingthe head 9 of the stud into the stud-receiving aperture, and, as bestillustrated in Fig. 4, the eam-shaped end 2() of the locking membercontacts with the edge of the socket adjacent the periphery of thestud-r`eceiving aperture, thus holding the locking member out of theaperture until the head 9 has passed therethrough and the neck has beenengaged therewith. The

ning

spring 14 then urges the locking member forward and the socket-engagingmember shifts relative to the stud-receiving aperture to engage the neckthereof with the periphery of the stud-receiving aperture, thereby topermit engagement ofthe fin-like part` 12 of thelo`eking` member withthe` stud-receiving" aperture,' as "best illustrated Then in theposition illustrated'. in this figure, the stud is looked with the inFig. 2.

thereon, which causes theback plate and 17 relative to thesocket-engaging member. Thus the `reversely bent ortion Aof 'the backplate adjacent the tin-li e part 12'engages the depending linger 19 and'.moves 4the lockingmember relative to thesooket-engaging memberuntilythe cam-shaped portiony 2O is adjacent the periphery of thestud-re ceivilngy aperture, `as best .illustrated in Fig. 3. I i

Then asa further pull is exerted upon the curtainthe socketenga ingmeans may tip relative to the socket and become disengaged therefrom. gThis relative tipping movement between the clench plateyand the outerend of the socket-engaging member is ermitted b theelongated,slotfprovidedin t e face of tliye, cleneh plate.I Thus the rstpart of the tipping action releases the locking member softhat Athe last4part, of the tipping action :tips the socket-engagingnhead outoflengagement'withthe socket. i While I yhave shown and described .apreferred `form of one embodimentoi my inclench plate or casing to tipabout the pivot vention, it .will Abe understood that changes involvingomission, alteration, substitution and reversal of parts, and evenchangesl'n the mode of operation, may be made Without departing from theseopeof my invention which is best defined in the followingelaims.
